attribute parsing problem

[Gary Hughes]

I have a strange problem, the following document fails to parse with the following message:   <?xml version="1.0" encoding="UTF-8"?> <response price_step_up="0" vwap="0"/>   > ./DOMPrint g.xml Fatal Error at file "g.xml", line 2, column 34    Message: The attribute 'vwap' is already used in element 'response' >   If I change either of the attribute names slightly then it works fine, I haven’t seen anything like this before. It began when I added the price_step_up attribute to some documents, looks like a string hashing function is not working correctly maybe?   I’m using xerces 2.4 on solaris with gcc 3.3.   Gary.
